To address the requirements, MPEG decided to define two different system stream formats with maximum commonality, the MPEG-2 program stream (PS) format for use on relatively error free media such as optical discs and the MPEG-2 transport stream (TS) format for use on error prone media, such...
...比起 MPEG-2 第二部分和第一版的 H.263,它的压缩性能有所提高。 MPEG-4 第十部分,等同于 H.264,是这两个编码组织合作诞生的标准。...2000 年,MPEG-4 标准出现后,AAC 重新集成了其特性,加入了 SBR 技术和 PS 技术,为了区别于传统的 MPEG-2 AAC 又称为 MPEG-4 AAC。
主要是针对从视频采集卡中出采的两路实时MPEG-2 PS流进行了拼接研究及实现.在拼接过程中,通过正确选取拼接点,对系统参数如PTS,DTS等进行调整达到了视频流的连续播放效果,通过对视频帧的即时前向查找,避免了传统方法下通过等待查找可能造成的缓冲器下溢问题,并通过vbv_delay参数的前后关联性,解决了缓冲器的上溢等问题...
